` REEL-Hines.

To all whom t may concern Be it known thatI, EMIL E. TUcrioLKE, acitizen of the United States, residing at Labolt, in the county of Grantand State rof South Dakota, have invented a new and useful Reel-Hinge;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable ot-hers skilled in theart to which it appertains to make and use the same.

This invention relates to harvester-reels, and particularly to a new anduseful hinge for the arms for such reels.

The main object of the invention is to provide a hinge, capable offlexing in one or more directions.

The invention comprises further features and combination of parts, ashereinafter set forth, shown in the drawings and claimed.

In the drawings Figure 1 is a view in elevation, showing a flexiblehinge connec tion, constructed in accordance with the invention, andapplied between two members. Fig. 2 is a similar view, taken at rightangles to Fig. 1. Fig. 3 is a view in perspective of various parts ofthe iieXible hinge connection disassembled, showing the springs of theconnection omitted.

Referring more especially to the drawings 1 and 2 designate two members,which compose the arms of the harvester reel. IThese two members areconnected together by the flexible hinge connection, 3. This hingeconnection consists of the two plates 4 and 5, which are angular incross section, as shownx Projecting from the sides 6 of the plates 4 and5 are two apertured ears 7 and 8, which are disposed in registration.Passing through the ears 7 and 8 is a bolt 9, having a nut 10 threadedon its end. The diameter of the bolt 9 is less than the diameters of theapertures of the ears 7 and 8. Arranged on the bolt 9 is a washer 11,and encircling the bolt between the ears 7 and 8 and the washer a coilspring 12 is arranged.

EXtending at right angles to the sides 18' of the plates 4 and 5 are twoears 14 and 15Y rEhe planes of these ears are at right angles to thoseof the ears 7 and 8. Passing through the ears 14 and 15 is a bolt 16, onthe end of which a nut 17 is threaded. Adjacent the nut a washer 18 isdisposed. Between the washer 18 and one of the ears 14 plates 4 and 5are secured to the members Specification of Letters Patent.

1 and 2, by means of the bolts 20, as shown. rIhe apertures of theears14 and 15 are larger in diameter than the shank of the bolt, whichpasses through them.

By making the apertures of the ears 7 and 8 and the ears 14 and 15larger in diameter than the bolts, the plates 4 and 5 may flex in morethan one direction. When the members are worked on the pivot bolt 9 thetension of the spring 19 is exercised, and when the members are ieXed atright angles to the first eXing both springs are under tension.

By the provision of such a hinge the members 1 of the arms of the reelare allowed to flex in one or more directions, and as shown in Fig. 1 ofthe drawings, which eXing is caused by the resistance of the grain incontact with the members 1, thus deflecting or carrying the standinggrain upon the platform (not shown) of t-he harvester. The arms and themember 1 tend to raise the fallen grain into position, for cuttingaction by the sickle (not shown) of the harvester (not shown).

From the foregoing it will be noted that there has been devised aneiiicient, simple and practical flexible hinge.

The invention having been set forth, what is claimed as new and usefulis 1. In a harvester reel having radial arms, each arm comprising twomembers, one immovable relative to the reel, while the other constitutesan outer movable tip member having a iiexible hinge connection with theouter end of the immovable member, the flexible connection being soconstructed, so as to constitute means to permit the tip member to movein three directions, under the resistance of the grain.

2. In a harvester reel having radial arms, each arm comprising twomembers, one immovable relative to the reel, while the other constitutesan outer movable tip member having a flexible hinge connection with theouter end of the immovable member, the hinge connection comprising apair of metal angle plates, each plate having apertured ears arranged inplanes at right angles to each other, the corresponding ears of eachplate being arranged in registration, bolts passing through theregistered ears and provided with coiled springs, and means on the boltsfor regulating the tension of the springs.

3. In a harvester reel having radial arms,

outer end of the immovable member, the

hinge Connection Comprising a pair of metal angle plates, each platehaving apertured ears arranged in planes at right angles to each other,the corresponding ears of each 10 plate being arranged in registration,a pair of bolts arranged in planes at right angles Copies of this patentmay be obtained for ve cents ealclf, by vmidessing` the Go'mmfssibnr ofPatents,

to each other and passing through the registered ears, springs on thebolts7 and nuts threaded on the free ends of the bolts for regulatingthe tension of the springs.

In testimony whereof I have signed my nal-ne to this speeiication in thepresence of two subscribing witnesses.
